My present invention relates to a printing In the top of frame 2 is rigidly secured an mechanism, and more particularly to a deaxle 3 on which are revolubly mounted a set vice comprising type wheels adapted for of five type wheels, the face of the first of I actuationby clock .set mechanism and for which is the meridian wheel (reference nuusewith a coin controlled machine for selling meral 4) and bears at regular intervals the accident'insurance, in. which it is necessary insignias A.

On the side of each wheel is a meridian wheel, and Fig. 5 the back of the flange 4 5*, 6, 7 and 8 having peripheral same wheel; Fig. 6 the front and edge and pockets 4 5 6 7 and 8 therein in Fig; 7 the back of the wheel bearing the hour which the heads of arms 45-6-7 and numerals and Fig. 8 the front and edge; 8 loosely mounted on a cross rod 9 in frame Fig.9the back of the wheel bearing units day 2 are yleldingly held by springs 45 numerals. -Fig. 10 the front and edge, and 67- and 8 so that after each wheel Fig. '11 the back ofthe wheels bearing tens has been forwarded by the mechanism day numerals; Fig. 12 the front and edge, which will presently be described it will be osition indicated.

Revolubly mounted on axle 3, on each side of the type wheels, an arm of a yoke 12. Mounted in the sides of yoke 12 is a rod 13, and axially mounted on rod 13 is a bracket 14 having fingers 4 5 6 7 and 8 of graduating length and extending in line with the ratchet flanges on the several type wheels. On rod 13 is wound a spring 15 which yieldingly re tains bracket 14 in the direction of the type wheels. Pivoted on a pin 16 on one of the sides of yoke 12 is a lever arm 17 which is connected in a suitable manner with the clockwork so as to be lowered and raised at the com letion of each hour. The lever 17 in turn owers and raises the yoke 12 carrying the bracket 14. As bracket 14 is low ered, its second tooth 5 is pressed into a notch in the periphery of flange 5 and as the bracket is raised, wheel 5 is carried around until a succeeding )air of numerals is in position beneath the po icy slip previously referred to.

With each action of bracket 14 wheel 5 is moved forward one space until the wheel having started with the duplicate numerals 1 on top, the duplicate numerals 12 have reached the stamping position; when bracket 14 drops down to carry the duplicate numerals 1 to the top again, finger 5* drops into a notch 5 which is deep enough to permit the first finger 4 on bracket 14 which is shorter than finger 5 and normally out of contact with its flange to drop into a shallow notch 4 on flange 4 so that both wheels 5 and 4 are carried around and the type wheels instead of presenting a face reading 12 a. m., will present the face 1 p. m. The second wheel 5 is again operated at the end of each hour until the face of the two wheels mentioned read 12 p. 111'. when the finger 5 b drops again into notch 5 and finger 4 drops into the notch 4 which is deep enough to permit the finger 6 which is shorter than fingers 4 and 5 and normally out of contact with its flange, to drop into a notch 6 in flange 6 so that the next operation will move the three wheels On the sides of the wheels oppol are integral flanges I l movement of the wheels they would read 21 is day of the year,

forward to record a new day; the third wheel bearing duplicate numerals from 1 to O and the three wheels before the last action mentioned, reading 112 p. m., the numeral 1 representing the day of the year and the other, the hour was twelve oclock p. m.; after the a. m., the numeral 2 representing the second and the others that it was 1 oclock a. m. After wheel 6 has been forwarded until the figure 9 is uppermost, at the next operation of bracket 14 finger 6 drops into a notch 6 in flange 6 which is sulficiently deep to allow the finger 7 which is shorter than finger 6 5 and 4 to dro into a notch 7 in the fourth wheel 7, which latter bears a set of duplicate numerals from 1 to 0, and forms the tens column in the day numerals. When the bracket 14 is then raised, the four wheels mentioned are brought forward and show a face reading 101 a. m., meaning that it is 1 a. m. on the tenth day of the year. At each complete revolution of wheel 6, wheel 7 is advanced one space until the numerals 99-12 p. 1n. are at the top when, the bracket being lowered, finger 7 b drops into a notch 7 Y which is of suflicient depth to permit the finger 8 which is the shortest finger on the bracket, to drop into a notch 8 in flange 8 when, upon bracket 14 being raised the entire set of five wheels will be forwarded and the record face of the type will read 1001 a. m., meaning that it is one a. m. of the one hundredth day of the year. After each complete revolution of the wheel 7, wheel 8 an be forwarded one space, in the manner described, until the year has ended, when it is necessary to open the machine and turn the parts back to their starting point byhand.

Claim.

In a device of the character described, a plurality of revoluble type wheels arranged side by side and provided with type members on their peri heries the type members of each wheel being arranged in peripheral duplicates and the two members of each duplicate being adapted to print simultaneously.

In testimony whereof I aflix my signature in presence of two witnesses.
